----------------- Introduction
Overview
The KVM Switch SW0206C, SW0207A, SW0407C and
SW0408A are computer switches that allow access to
two or four IBM compatible computers from one PS/2
keyboard, mouse and monitor. Switching between
computers is as easy as pressing the push button or
entering hot-key commands from your keyboard. There
is no interface card and software to install and the switch
is independent of the computer operating system.
Ready to run right out of the box, this kit comes with
everything you need - a switch and complete cable sets,
just hook them up and go. By allowing one console to
manage all your computers, the SW0206C, SW0207A,
SW0407C and SW0408A eliminate the expense for extra
consoles, the spaces for extra peripherals and the time
hopping around for accessing different computers.
SW0207A allows one microphone and speaker to be
shared by two computers and SW0408A allows four.
